The Signal Group 250 Portable cooler dryer removes water vapour from stack and exhaust emission gases, before analysis by ambient analysers. Errors due to water interference are removed and condensation is prevented from occurring inside the analyser.
The 250 features a semiconductor Peltier cooling system with an aluminium cooling block. Fitted into the block is then a high efficiency heat exchanger made of stainless steel. The condensed water is then removed using a continuous peristaltic pump.
The status of the cooler is indicated by an LED system with high temperature alarm, a water alarm and an indicator that the set temperature is being maintained.
